The Coherent Magnetic Field of the Milky Way [PDF]
The Astrophysical Journal, 2023 We present a suite of models of the coherent magnetic field of the Galaxy based on new divergence-free parametric functions describing the global structure of the field.

Detection of the Keplerian decline in the Milky Way rotation curve [PDF]
Astronomy & Astrophysics, 2023 Our position inside the Galactic disc had prevented us from establishing an accurate rotation curve, until the advent of Gaia, whose third data release (Gaia DR3) made it possible to specify it up to twice the optical radius.

The Global Dynamical Atlas of the Milky Way Mergers: Constraints from Gaia EDR3–based Orbits of Globular Clusters, Stellar Streams, and Satellite Galaxies [PDF]
Astrophysical Journal, 2022 The Milky Way halo was predominantly formed by the merging of numerous progenitor galaxies. However, our knowledge of this process is still incomplete, especially in regard to the total number of mergers, their global dynamical properties and their ...

Unveiling the time evolution of chemical abundances across the Milky Way disk with APOGEE [PDF]
Monthly notices of the Royal Astronomical Society, 2023 Chemical abundances are an essential tool in untangling the Milky Way’s enrichment history. However, the evolution of the interstellar medium abundance gradient with cosmic time is lost as a result of radial mixing processes.

The integrated metallicity profile of the Milky Way [PDF]
Nature Astronomy, 2023 The authors compute the gradient of the Milky Way’s heavy elements as though they were viewing our Galaxy from the outside. This will allow astronomers to compare Galactic measurements with those for other galaxies to understand how typical the Milky Way

Albatross: A scalable simulation-based inference pipeline for analysing stellar streams in the Milky Way [PDF]
Monthly notices of the Royal Astronomical Society, 2023 Stellar streams are potentially a very sensitive observational probe of galactic astrophysics, as well as the dark matter population in the Milky Way.

The period–luminosity relation for Mira variables in the Milky Way using Gaia DR3: A further distance anchor for H0 [PDF]
Monthly notices of the Royal Astronomical Society, 2023 Gaia DR3 parallaxes are used to calibrate preliminary period–luminosity relations of O-rich Mira variables in the 2MASS J, H and Ks bands using a probabilistic model accounting for variations in the parallax zeropoint and underestimation of the ...
